I think the oem fluid is 75W-80.
If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certification seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient

oem fluid is more expensive here, and in hot summer sometimes it feels to thin. I would like to try it if it will make shifts smoother , sometimes (very rarely) i do get a little grind from first to second gear 
.I just want to know is it safe to use in ap1 tranny because it says both APIGL-4 and 5. people at Motul are recomending it now for ap1 also cause they have changed the formula to suit GL-4 trannys also.
you wont get that crunching sound

It worked great for me its a little stiff when cold but once you start hitting vtec and shift often it gets creamier and creamier 
love it....
I was thinking of trying redline mt90 but i changed my mind....motul works for me so il stick to that im also using it in my diff Motul competition 75w140

The oil you listed is for hypoid gears. It has additives that are not suited for the synchos in the trans and should not be used there. There are oils with the right viscosity that can be used in the trans, like Red Line MT 90 which does not have these additives it it.

Here's some interesting info copied from Bob is the Oil Guy:
Updated List of Dedicated MTF Fluids | Bob Is The Oil Guy
Here is an updated list of dedicated GL-4 and a few GL-5 MTL's.
Much confusion over the viscosities (thickness) of MTF fluids is the result of the SAE gear oil charts and its ranges seen at:
BITOG Viscosity Chart
NOTE: This list is only a “suggested” list of MTFs. It is not an endorsement of any one fluid, nor is it implied that any one fluid will cure problems in MTs that have design problems or those that have excessive wear.
A. These MTL fluids are closest to a Kinematic Viscosity of 6.x cSt@100C (About the same viscosity as a DexronVI) and SAE 70 or so are:
1. Castrol Syntrans FE 75W,
2. BMW (Pentosin) MTF-LT-3,
3. Honda MTII or MTF 2.
4. Ford FML-XT-11-QDC
5. Volvo Manual Transmission Fluid (6.4 cSt) [Recommended for: type M65 5-speed with 6-cyl. engine, M66, MTX75 and MMT6 and of the type M56, M58 and M59 from and including model year 1996. Meets Ford specification WSSM2C200-D2]
B. The next higher viscosity MTL would be the 7.0 to 7.5 cSt@100C versions [SAE 70W75] (About the same viscosity as the original DexronIII/Merc)
1. Royal Purple's Synchromax
2. Ravenol MTF-2
3. Honda MTF
4. VW part number G052512A2
5. GM Manual Transmission and Transfer Case Fluid
6. BMW (Pentosin MTF 2) MTF-LT-1, 2 ,3
7. Tutelo (Petronus, Italy, Product Code 1402)
8. Pentosin Pro Gear 70W75 (Australia)
9.0 Pentosin FFL-4
10. Redline Power Steering Fluid
C. The next higher viscosity MTL would be Castrol Syntrans V FE 75W-80 8.0cSt
D. Redline DCTF Dual Clutch Transmission Fluid (8.1 cSt)
E. The next higher viscosity MTL would be BG Synchroshift II (8.2 cSt)
F. The next higher viscosity is Mopar Type MS-9417 MTL 9.0cSt
F. Valvoline MTF Part Number 811095 9.2 cSt
G. The next higher viscosity MTL would be Pennzoil Synchromesh 9.3 cSt
H. The next group of MTL’s are in the 10.x cSt (SAE 75W80) range:
1. Redline MTL 75W80
2. Amsoil MTF (9.7 cSt)
3. GM Synchromesh’s
4. Volvo MTF 645
5. Fuchs TITAN SINTOFLUID SAE 75W-80 synthetic MTF (Carries a GL-5 rating as well)
6. Lodexol (Morris Lubricants) MTF
7. Motylgear 75W-80
I. The next higher viscosity MTL would be a 12.0cSt@100C and SAE 75W85:
1. Redline MT-85 – 12.0 cSt
J. The next higher viscosity MTLs in the 14-15 cSt (SAE 75W90) range would be:
1. Amsoil MTG
2. Redline MT-90
3. Castrol Syntrans Multivehicle 75W-90
4. Castrol Syntrans Transaxle 75w-90
5. Ford XT-75W90-QGT (Carries a GL-5 rating as well)
6. Ford MOTORCRAFT® Full Synthetic Manual Transmission Fluid XT-M5-QS
7. Subaru Extra-S Gear & Transmission Fluid carries a GL-5 Rating because it is used in common sump driveline systems.
8. ACDelco 10-4059 GL-4 75W-90 Manual Transmission Fluid
9. ACDelco 89021806 For use in MA5 manual transmission for GMT 345, GMT 355 Trucks and GMX 020 Cobalt Pursuit and G5 Passenger only. Caution: Rated at GL-3 (ExxonMobil fluid).
I would try to stick to GL4/GL5 fluids with no more than 10cSt @100C 90 weight gear oil seems a bit too thick for the transmission.
